Recordings can't be read

Hi,
When I record my audio call with Jami, the files are effectively created, but I can’t read them.

When I open them with Audacity, they last 0.34 second and there’s no sound (cf. screenshot).

You can find one of the generated files here : https://file.io/yR9nmDbJm6hJ.

Thanks for your help :smiley:
